Use relative path when opening components.xml in the maintenance tool

Consider the following scenario:

I use my installer to install my software on a portable device (USB Stick). The drive letter is e.g. E:. The installer creates a MaintenanceTool.exe, everything seems to be fine.

Now I ship the USB-Stick to my customer and the drive letter is now e.g. F: When he starts the maintenance tool there will be an error, because the maintenance tool can't find E:\<path to components>\components.xml.

As components.xml is located in the same directory as the maintenance tool itself, there is (from my point of view) no need to use an absolute path name.
